FIG. 4 is a flow diagram illustrating a method for sensing according toone embodiment of the present invention. The method begins withpre-production 401. Pre-production comprises employing 402 a scriptand/or storyboard flowchart, or employing 403 a digital template 403. Aportion of this front-end may be implemented automatically or manuallyin software, comprising analysis, design, development, production,implementation or evaluation of script, storyboard, and/or digitaltemplate. Optionally, frames and/or scenes are labeled (via meta-data)according to script, storyboard, or digital template in use.

A script or storyboard is downloaded over a wired and/or wirelessnetwork, made available via removable storage (e.g. memory card and/ordisk), or is alternatively created on media appliance. A digitaltemplate describes how to construct a video and/or multimedia documentby sensing (i.e. “shooting” or recording) and assembling individualscenes and/or segments in particular order, and is downloaded over awired and/or wireless network or created on media appliance.Alternatively, user of media appliance 100 may decide not to consult ascript, storyboard, or digital template, and proceed directly to sensing404.

One example of a template is a template for insurance inspection ofvehicle accidents, wherein the template indicates “slots” for videoclips, taken from various angles, of the vehicles involved in theaccident, as prescribed by an insurance company.

Optionally, media appliance 100 adaptively guides media applianceoperator in making discretionary decisions to take alternate scriptpaths and/or alter flow of script (or storyboard or digital template) orgenerally deviate from the script, for example when dealing withemergency conditions and/or events which do not occur according toscript. Such guidance may employ non-deterministic scripts, according tologic specified using Bayesian modeling, neural networks, fuzzy logic,and/or other technique for making decisions under complex conditionsand/or under incomplete information. For example, in one embodiment acast member in a script is described by fuzzy attributes, such as “afemale actor with at least five years drama experience” in leading role(instead of or in addition of identifying the lead role actor by name).Then, in case the lead actor canceling her engagement, instructionsemploying fuzzy logic perform a search for actors matching the fuzzyattributes to dynamically recommend one or more candidates to fill therole.

Optionally, digital template or script is non-linear, allowing for oneor more branching points. A branching point allows the script and/ortemplate to flow in more than one path. For example, scene (or clip orstream) A can be followed by scene B or scene C, depending on whichbranch of the branching point following A is taken. For a viewer, amedia presentation prepared according to such non-linear template orscript allows for a multiplicity of presentations comprising differentscene (or clip or stream) orderings. For a viewer, the decision of whichof the alternate paths to follow in a branching point can be viewerselected, randomly chosen, based on external variable (such as acombination of one or more of: weather, temperature, stock quotes, timeof day or year, viewing location, amount of money left in viewer'saccount, or any other external variables), based on biometric sensing ofviewer, based on the result of an identity or emotion recognitionprocedure on viewer (such as distinguishing between happiness, sadness,excitement, apathy, interest in a particular aspect of the presentationand/or other emotions or indications of interest exhibited by viewer),based on real-time input from viewer or from larger audience (such asdeliberate viewer decision of which script or template path to takenext, provided via an input device or detected by the presentationmodule), or based on other variables. Such non-linear template or scriptallows for example for the production and presentation of a PG-rated,R-rated, or X-rated version of a given movie depending on the audience(for example a parent may elect to view the R-rated version of the moviewhile electing a PG-rated presentation for the children). As anotherexample, a wedding template or script may allow for differentpresentations based on whether the bride's family or the groom's familyis viewing. As another example, a mystery presentation may offeralternate endings, based on viewer input or external variables asdescribed above.

Media appliance 100 senses 404 video and/or audio and stores a digitalrepresentation in memory 110. Optionally, multiple audio and/or videostreams are sensed, either by the same media appliance or bycollaborating media appliances, wherein synchronization is provided forthe multiple streams, in the form of meta-data tags describing relatedscenes and/or streams and/or frames, and/or in the form of meta-datadescribing time stamps relating different scenes and/or streams. Forexample, memory 110 stores a data structure comprising one or morefields identifying one or more related video scenes and/or streamsand/or frames, and a field indicating the nature of the relation (forexample indicating that the video scenes and/or streams and/or framesrepresented different viewing angles of the same sensed object).

Media appliance 100 then post-produces the stored digitalrepresentation, using controller 108 and/or audio or video plugin storedin memory 110.

The post-produced digital representation is then stored 406 in memory110 (or in other storage medium such as optional on-appliance hard-diskor storage tape for storing data), displayed 407 on on-appliance displayunit 114, and/or sent for off-appliance display and/or exhibition (e.g.for IMAX display according to IMAX 15/70 format, or for TexasInstruments DLP (Digital Light Processing) format), or for digitalremastering according to IMAX's DMR (Digital Remastering) format, or forsatellite distribution (e.g. to Digital Audio Broadcast (DAB)distribution scheme to DAB enabled devices such as PDAs, cellularphones, personal audio and/or video players, or other devices forpresenting audio and/or video).

Upon sensing 601 a scene, the digitalrepresentation of the sensed scene is tagged 602 with meta-data.Meta-data comprises time, media appliance location (such as provided byGPS module 112), media appliance orientation and/or media applianceacceleration (such as provided by acceleration detector 113),multi-lingual features (allowing for translation, subtitles, voice-over,etc.), cues to a theater automation system (such as instructions forhouse lights to go up, half-way up, or down, or instructions to open orclose curtains, etc.), instructions for allowing or disallowing content(such as trailers or promotional clips) to play next to other similarcontent, information indicating suitability of content for differentaudiences such as children, information indicating any promotionaloffers, products and/or services (such as advertisements, productcatalogs and/or coupons for products and/or services), informationallowing for organizing and/or managing meta-data available toadvertisers and/or service providers, and/or other informationdescribing, identifying and/or relating to content. Tagging may be doneper scene, per frame, per audio and/or video stream (e.g. when multiplestreams are present), or per other defined segment of audio and/orvideo. For example, a video scene is tagged with meta-data comprising afield identifying the language used in the video scene. As anotherexample, a video stream is tagged with meta-data comprising a fieldindicating a warning against viewing by children.

FIG. 7 is a flow diagram illustrating a method for transferring dataand/or instructions from off-appliance source to on-appliance memory.After determining 701 off-appliance source, such as external repository(for templates, plugins, DRM data, encryption keys, media clips,security data, biometric data, GPS data, etc.), proceed by transferring702 data and/or instructions from determined off-appliance source toon-appliance memory 110.

In one embodiment, media appliance 100 is a member of a distributedgroup of media appliances 100, for example in a distributed network ofmedia appliances 100 and/or in a peer-to-peer configuration of mediaappliances 100. A media appliance 100 dynamically joins and/or leaves adistributed group of media appliances 100, in parallel and/or seriallywith other media appliances 100. Alternatively, media appliance 100initiates a distributed group of media appliances 100, allowing forother media appliance's 100 to dynamically join and/or leave the group.In one embodiment, the group of media appliances 100 collaborates tocover an event, such as a sporting event, a public political event (e.g.a rally), a family event (e.g. a wedding), or other event. Mediaappliances 100 tag sensed audio and/or video data as described above(e.g. with GPS information, time stamps, DRM meta-data, or otherinformation previously described), allowing reconstruction of coveredevent from the audio and/or video data collected by distributed mediaappliances 100. Memory 110 stores instructions and/or data forinitiating, joining, leaving and/or querying the status of orinformation about such a distributed group of media appliances 100.
